DC 5.5 2.1mm Battery Clamps Extension Cord - 2 PACK 12v Battery Alligator Clips Car Charger Power Supply Cord DC Connector Male Barrel Plug to Battery Clamp-on Charger Cable for Auto Accessories (5FT)

I've cut into this cable as I intend fitting a fuse holder (if you're going to use this on a lead-acid battery you should, too). This reveals that it appears to be 17AWG (approx. 1mm²) rather than 16AWG (approx. 1.3mm²); one of the pictures shows a 1mm² ferrule that I've crimped on one end to test. Looking online that's still good for 16 amps though, which is more than the DC power jack at the end is likely to take.The cable's generously insulated, appears to be pure copper (rather than copper clad aluminium rubbish), a useful length and the croc clips at the end seem decent.

I wanted these for the powerbanksYou get 2 of these.They are 60" longThe croc clip bit opens to 1" maximum and feels firm and the sleeves are a proper length and tightness to save them sliding off.Its sometimes a bit hit and miss with cables like this , whether you get a reasonable thickness to actually take the power they are advertised as , in this case they are a good girth. The cable to each clip is 1/8" thick so okay for 12 ish volts, obviously not for jump cable use which needs way more.The other end is a barrel connector which rather luckily fits our older power bank's input socket.This connector doesnt fit an ecoflow output port
